Impermanence looked at Xu Lai's pretending to be forced, holding back his chattering teeth, and sneering at the corners of his mouth, it is not who can accept the lowest temperature here, but how long can he stay in what kind of temperature. To put it simply, staying in minus 5 degrees water for an hour will have the same results as staying in minus 10 degrees water for half an hour. Of course, you can also stay in the pool of -100 degrees for 3 minutes, and as long as you are not dead, the results will be the same. Therefore, it is not only about physical acceptance, but also about durability. Because the longer the body is in this cold state, the more serious the heat loss in the body, which requires the trainee to either have a strong physique and can resist hard, or have a special ability to lower their own body temperature and reduce heat loss, or they have strong heat to offset this loss.

So Impermanence was waiting for Xu Lai to suddenly throw away the book and jump out of the water in a panic.

Old K looked nervous, and the tower was dumbfounded. They all came over like this, and it's not strange that they can resist it, but it's weird to resist so easily.

A minute passed, Xu Lai did not react, and five minutes passed, Xu Lai was still flipping through the book. An hour passed. Xu Lai has already finished reading this book. Close the book and get up from the pool. I opened the door and came out.

"You still think how good you are, you can't stand it?" Impermanence was already impatient, he had already adjusted to minus 5 degrees, and he also came out of the pool to replace the next one.

"Hehe, I just want to change the book. Since you're going to change the pool, I'll give you this minus 6 degrees. Xu Lai shook the book in his hand and said.

"No, I'm going to minus 8 degrees." Impermanence gritted his teeth and said.

Xu Lai wanted to say whatever you want, but he heard Tie Ta blurt out and stop: "No." You're almost at your limit, and you have to take it one step at a time. Stay inside each for 5 minutes before you can replace the next. ”

Xu Lai spread his hands, changed another book, and jumped into the pool at minus 7 degrees. Every time the temperature drops by one degree, there is a big difference, which means that the body heat loss is accelerated, and the quenching technique also needs to be nutritious, Xu Lai feels that the little things he ate in the morning have been consumed, and it is time to eat again.

Suddenly, a medicinal force in the body was stimulated. This medicinal power is very objective compared to his current physical strength.

Xu Lai was pleasantly surprised. Unexpectedly, he didn't digest the medicinal power of the Spotted Dragon Baibu Pill at that time, and hid it in his body. If it weren't for this quenching, I'm afraid that this thousand immortal yuan coins would have been spent in vain.

Xu Lai was pleasantly surprised and grinned.

Impermanence also entered the pool at minus 6 degrees, and when he saw Xu Lai grinning, he thought he was laughing at himself.

"I don't believe it, my special ability of the ice attribute can't compare to you here." Impermanence is ruthless in his heart.

The body has nutrients, and Xu Lai feels that it can't be wasted. Quickly got up from the pool, quickly ran to the edge of the pool at minus 10 degrees, and jumped in.

"Hey~" Old K glared and stretched out his hand, looking like he wanted to stop it. He saw Xu Lai's very leisurely appearance just now, and the monitoring room didn't call him to the police, so he planned to get a stool to come over.

Who wants Xu to suddenly change the pool. And there are two pools at once. He was too far away to stop him, and it was too late to shout. Xu Lai had already jumped in, and although it was very uncomfortable to look like that, he could still hold on. didn't say anything more, sat on the edge of the hut with a stool, and guarded Xu Lai to prevent him from skipping a grade again, it was too dangerous.

"......" Impermanence only felt that Xu Lai had disappeared in front of him, and through the transparent glass, he saw that Xu Lai had changed to a pool of minus 10 degrees. With a fire in his heart, he looked at the tower.

The tower scratched its head, turning its head not to see impermanence. The heart of the Taoist family is personally led by the bishop, and the requirements are naturally different.

When the quenching technique is running, there is a tingling sensation, but after a long time, you will like this feeling. Because after the itching, the body will feel relaxed and powerful. After adapting to this temperature, only the pleasure of quenching is left.

So Xu Lai felt the sourness brought by this kind of body tempering while reading a book.

Another hour later, Xu Lai's second book was finished. It's also time for lunch.

Because a few of them are training here, the small cafeteria brings the food. They are all great tonic medicinal diets.

Now the impermanence is also gobbled up, and the demeanor is gone, because soaking in ice water, the calorie consumption is very large, and if you don't eat enough, you will not be able to withstand it in the afternoon.

Xu Lai still had a large amount of food, and he didn't leave any of the rest of the food, so he let him eat it all alone.

This time, Impermanence did not despise Xu Lai, who ate too much.

In the afternoon, Xu Lai continued to read, fixed in the pool at minus 15 degrees, he didn't change the pool, because he tried it, no matter how low the temperature was, the effect of the quenching technique would not only not increase, but decrease, and it would damage the body. minus 15 degrees Celsius is like the apex of a parabola, which is the best quenching temperature at this stage.

Half of the dozen or so books have been read, and Xu Lai decided to continue reading after dinner. I'll finish reading it today, and the venue after that will not be very suitable for concentrating on reading. The high-temperature lab will burn the book.

You can change the venue early tomorrow morning.

For example, if you stay in a pool at minus 10 degrees for 10 hours, you can get A, 80 points or more, get B, and get C if you score 60 points or more. Xu Lai was almost enough, but he felt that his body still needed to be tempered at this temperature for a while, so he simply soaked in it and finished reading the book.

Impermanence couldn't hold on for a long time, sitting in the rest area, facing a book, but distraught.

Where you do best, you're trampled underfoot. Proud as he was, he had ever suffered such a blow. He didn't want to go to see Xu Lai, but his uncontrollable gaze shifted from the book to Xu Lai. Seeing that Xu Lai was still soaking in the pool, holding a book in his left hand and turning the pages quickly with his right hand. This is a sign of a super memory. He can do it too, albeit not as fast.

But he's upset now. Looking at the book in front of me, I really wanted to tear it.

The tower saw it in his eyes, and said angrily: "I think you should change places." You won't even be able to finish reading these books. ”

Impermanence looks reluctant, doesn't this mean that he has lost a mess. He didn't want to go like this, he planned to work hard after dinner, and strive to sit in the pool at minus 10 degrees for 3 hours.

"Admitting that you are inferior to others is a kind of courage, but also a kind of wisdom." Old K said meaningfully, and then said to the tower: "Take him to another laboratory to have a look, and dinner will be over there." ”

The bishop spoke, and he also sent himself a very philosophical sentence, no matter how angry he was, he didn't dare to speak in front of Lao K. Obediently followed the tower.

Xu Lai ate a lot of food for dinner, which was specially given to him by Lao K in the small canteen, and it was full of medicinal power.

At ten o'clock in the evening, Xu Lai felt that it would not be much effect for him to stay here any longer, and when he finished reading the book, he got up from the pool.

The sleepy old K was woken up, "Why did you come out?" Not sitting in it anymore? ”

"I've got an A, I've finished reading the book, I'm going back to sleep." Xu Lai said with a look of course.

“……”

"No way?" Xu came to see that Lao K didn't speak and asked.

"Do you still have time to sleep? Do you think you're getting nine out of ten in the assessment? Old K said with a toothache on his face. As an instructor, with Xu Lai's age, he is the strength of the yellow level, and he is a little admired for having this kind of training intensity, after all, he was not so strong at that time. But he can't say you go to sleep, that's not what the instructor should say.

"Forget it, I'll change the lab". Xu Lai said curtly, if you don't sleep, don't sleep, anyway, because the body has just been quenched, the body cells are excited.
